Bruce Wayne (Jason O'Mara Jason O'Mara) walks alone on the road of light and darkness with the appearance of a glamorous rich man and a Batman cloak on the other. In order to prevent Damien, a descendant of the League of Assassins (voiced by Stuart Allen Stuart Allan), he trained Damien hard and strictly. Until the pursuit of psychopath Dollmaker, the villain was killed by owl Talon (voiced by Jeremy Sixto Jeremy Sisto), but Batman once thought Robin did it, which made Damien's dissatisfaction and resentment grow day by day. With the passage of time, the differences and misunderstandings between Bruce and Damien seem to be getting deeper and deeper, and the confusion in the teenager's heart deepens with the re-emergence of Talon. This pair of father and son are doomed to go through the most difficult period of running-in.
